JOINT FOR PIPING.

Application filed May 17,1900.

To all whom it may concern;

Be it known that I, JOHN WILLIAM WIG- GINS, residing at Savannahfln the county of Chatham and State of Georgia, have made certain new and useful Improvements in Joints for Piping, of which the following is a specification.

My invention is an improvement in joints for piping for use in the plumbing business for connecting pipes, such as lead and castiron soil and vent pipes, together; and the invention consists in certain novel constructions and combinations of parts, as will b In the drawings, Figure 1 is a vertical longitudinal section of a joint embodying my invention. Fig. 2 is a detail longitudinal'section of a joint-ferrule having its bore of uniform diameter. Fig. 3 is a side view of the ferrule shown in Fig. 2. Fig. 4 is across-section on about line 4 4 of Fig. 3, and Figs. 5 and 6 are respectively longitudinal section and side views of a joint-ferrule having atapering bore.

The ferrule A may be made of brass, castiron, or other suitable metal that will stand the test and requirement of the city in which the ferrule is to be used. In practice it is my purpose to make the ferrule of different metals to meet all the requirements of the different city ordinances, and in light, standard, and extra-heavy weight'to meet all requirements.

The ferrule A (shown in Figs. 2 and 3) has its bore B of uniform diameter and is provided at one end with the exteriorly-smooth surface 0 for a short'distance from its point D and tapers gradually from its point D, enlarging toward its head or fiangeE. I This flange E provides a shoulder E at its inner edge, which forms a stop in driving the ferrule into a lead pipe and also forms a seat for the calking material in the production of the joint shown in Fig. 1. The portion of the ferrule between the smooth ring 0 and the flange E is corrugated or ribbed longitudinally at l, producing a roughened surface for engagement by the interior of the lead pipe when the ferrule is applied thereto, as shown in Fig. 1.

In Figs. 5 and 6 the ferrule is shown sub- Srialllo.17, 063. (No modeLJ 2 and 3, except that the bore is tapered, gradually reducing toward the point end of the ferrule, and a greater inclination or taper is ready to be calked in the fitting F. (Shown in- Fig. 1.) It will be noticed that the ferrule by reason of its construction is quite rigid within the lead pipe before the yarn is inserted at G before calking at H; also, that the end of the ferrule is so made that when theconnection is completed the joint is perfectly smooth on the inside,which is an important feature from a sanitary standpoint and an improvement over the wiped joint, for it is seldom that a plumber gets a uniform surface on the inside of a wiped joint, and a small obstruction is liable to catch anything passing through the pipe. The longitudinal ribs or corrugations I operate to keep the ferrule rigidly in position and prevent it from moving rotarily in the lead pipe, as well as materially strengthen the ferrule, while the tapered exterior of the ferrule enables it to be readily fitted. to any ordinary sizeof lead pipe.

The joint may be effected as shown in Fig. 1, wherein the lead pipe, with the attached ferrule, is inserted in the fitting'F and the yarn G and calking H applied to complete the joint, as shown in the said figure.

I-Iavingthusdescribed myinvention, What I claim, and desire to secure by Letters Pat ent, is I i 1.. A joint substantially as described comprising the pipe-sections, the ferrule tapered fromend to end and having an end flange or shoulder and inserted in one of the pipe-sections and fitted therewith in the fitting of the other pipe-section, and the calking completing the joint substantially as set forth.
